Application filed April 8, 1927. Serial No. 182,145;

o n This lnventlon. rotates to valves. and :tts

primary object is to; providea reserve sup ply valve for fueltanks of vehicles and the like, vof a type whereby a predetermined quantity of fuel can he retained in the fuel tank for emergency use and released; at the will of the operator. a

A further object or the invention is to pro-- vide a reserve the]; supply device for tanks, that is, extremely simplenini construction inexpensive to, manufacture and capable of adjustment so; that variousqratntities of fuel can be retained in a tank equipped withthe device v the quantity retained heing'inam cordance with the desires oil the user. Another object oit the invention is to provide a reserve fuel supply device for vehicle fuel tanks that is capable or adjustment and operation in an easy and expeditionsvmam ner. a

This invention also consists in certain other features 015 construction and in the combination and arrangement of the several! parts to be hereinafter fully describedaillustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing'my invention in detail, reference will be had to the accompanying drawings wherein like characters: denote like or 3 corresponding pzartsuthroughout the several views, and in which: t Figure 1 1s a vertical sectional view taken through a fuel: tank of a vehicle equipped with my device and showing the same in sec-= tion and in; elevation.

Figure 2 shows perspective views oiisome of the parts of'mydevice. I v i Figure 3 is a sectional view taken-on line 3+3 of Figure 1 looking inthe direction of the arrows.

Figure 4 is a vertical sectional View taken through a slightly modified form.

Referring to the drawings in detail the letter A indicates a fuel tank formed with the usual interiorly threaded neck- B to threadedly accommodate the cap C which forms a part of a gage construction D. The above construction is conventional and is generally included as regular equipment on fuel tanks of motor vehicles, while my invention includes a cup 1 which is soldered or otherwise secured in the bottom of the fuel tank A as shown in Figure 1, and this cup is provided with a plurality of slots 2 formed in its side wall, for a purpose which will be presently apparent. The cup 1 is provided with the vac m apparent.

with flat surface '3' which has arranged adrjracentits loaveredgo anopenilng to accent" moda te one end of a fuel line 4 whichis adapted to be arranged in communication tank or carburetor of a vehicle. g

The cup 1 is disposed directly below the neck B and arranged in said cap for verti+ cal movement a sleeve" 5 having a flat" sur-- face 6 adaptedto engage withithe inner side or the flat surface 3' of the cup so as to prevent rotation of the sleeve in the cup will i he readily apparent. The flat surface 6 of the sleeve is providedfiwith an opening 7 adapted to register with the-openingof the flat surface 3 when the sleeve 5 disposed l i 111 Its normalposition as shown in rgure: I,

and formed integralwith and projectingl'at erally from said sleeveabove the flat SUIT-4 face 6' thereof, is an arm 8* rovided with a'slot Qadjarient its outer end.

Arranged for slid'ah l'e-movement through c an opening formed inthe top of the-tank A and through aboss lOis a rod llwhic-h 30 i i has its lower end reduced as at 12 to be received 111 the slot 9 and is secured therein through the instrumentality ot'a cotter-pin 13. In order to limit theupwa rd movement or the rod 11 there is adjust-ably secured 35 thereon through the instrumentality of a set screwild, a collarlo'which of course will engage the inner side of the top of the tank M when the rod is arranged as will be readily The sleeve 5 is threaded for aportion of its length; as at 116' to threacl'ed l y receive an adjusting collar 17 whichhasformed on outer surface channel guides 18 which are adapted to accommodate vertically disposed rods 19 formed with the cap C having their respective ends fixed to the top and bottom of the tank A. The upper ends of the rods 19 are offset in opposed relation with respect to each other.

From the above description and disclosure of the drawings it will be obvious that the sleeve 5 is adapted to be vertically moved in its cup 1 through the instrumentality of the rod 11 which has formed ,on its upper end a knob 20 for the purpose of operating the same, and when the sleeve 5 is in its normal position, it covers the slots 2 in a manner to form a tight joint and prevent fuel from passing into the sleeve through the slots 2. However, when the rod 11 is pulled it will elevate the sleeve 5 above the slots 2 which will result in the passage of the fuel through the slot and thence into the fuel line 4. The collar 17 can be adjusted on the thread 16 ofthe sleeve so as to vary the quantity of reserved fuel, as it will be apparent that when the collar is in its louermost position. the reserved quantity of fuel is much less than when the collar is in its uppermost position. The sleeve is preferably provided with gra'duations not shown so that the quantity of reserved fuel can be regulated in accordance with the desires of the user and in order to regulate the adjusting collar 17, the cap C is removed, the collarl5 is then made loose on the rod ll so that the rod can be elevated to an extent to place the collar in convenient reach wherebyit can be rotated on the thread 16. When the sleeve 5 is in its normal position as shown in Figure 1, the level of the reserve fuel will be at the top of-the collar 17 'In Figure 4 I have shown a slightly modi- "fied form of cup which is indicated by the reference numeral 21. The cup in this form isTalso provided with slots 22 in its side walls. but the fuel line 23passes through the bottom ofthe tank A and is connected with i the bottom of the cup 21.

inthescope ,of the appended claims.

What I claim is:

:1. The combination with a tank. of a reserve supply device associated with said tank and comprising a slotted cup fixed in the bottom of said tank, a sleeve mounted for vvertical slidable movement in said cup and controlling the slots therein. means carried by said sleeve for regulating the amount of reserve, fuel, a pipe line in communication with said cup, and. a rod secured to said sleeve and being mounted for slidable movement through saidtank, a knob on the outer end of said rod and a collar on said rod to limit the outer movement thereof.

2. The combination with a fuel tank. of a reserve fuel supply device comprising a cup fixed to the bottom of said tank and being formed in its sides with a plurality of slots, a fiat portion included in said cup and being provided with an opening. a pipe line connected with said opening, a sleeve threaded for a portion of its length and mounted for slidable movement in said cup in a manner to open and close the slots, means for moving'said sleeve and having a portion thereof arranged exteriorly of said tank. means to limit the movement of said sleeve and being adjustably fixed to the first mentioned lllQallSv means formed on said sleeve and associated with the fiat portion to prevent rotation of the sleeve, and an adjusting collar received on the threaded portion of said sleeve for regulating the amount of reserve fuel in said tank. 1 i

3. The combination with a reserve fuel device for said tank and comprising a slotted cup secured to the bottom of said tank and rising therefrom said cup being provided with slots-in its side wall. a threaded sleeve mounted for vertical movea fuel tank. of

ment in said cup and being adapted to coin WILSON C. HATFIELD.
